WARNING! Never hose off your wheelchair or place it in direct contact with water. Your wheelchair has a painted finish that allows it to be easily wiped clean with a damp cloth.

WARNING! Never use any chemicals to clean a vinyl seat, as they may cause the seat to become slippery or dry out and crack. Use soapy water and dry the seat thoroughly.

Wheel Replacement

Your wheelchair may be equipped with a tire and tube, tire and flat-free insert, or a solid polyurethane tire. Replacement tires, tubes, inserts, and tire assemblies are readily available through your Quantum Rehab Provider.

WARNING! The wheels on your wheelchair should only be serviced or replaced by a Quantum Rehab Provider or a qualified technician.

WARNING! When changing a tire, remove the entire drive wheel. If any further disassembly is required, deflate the tire completely or it may explode.

To replace a pneumatic tire tube, flat-free insert, or solid polyurethane tire:

1.Remove the drive wheel from the frame. See figure 13.

2.If equipped with pneumatic tires, make sure that the tube is deflated completely.

3.Use several tire levers to pry the tire from the rim. Tire levers are available from a bicycle shop.

NOTE: If your wheelchair is equipped with solid polyurethane tires, then no further disassembly is required. Go to step 7.

4.Remove the old tube or flat-free insert.

5.If equipped with pneumatic tires, inflate the new tube with enough air so that it just starts to take shape.

6.If equipped with pneumatic tires or flat-free inserts, install the tube or flat-free insert into the tire.

7.Use the tire levers to secure the tire back onto the rim.

8.If equipped with pneumatic tires, inflate the tire to the psi/bar/kPa air pressure recommended on the sidewall. Always use a regulated air source.

9.Reinstall the drive wheel to the frame. Make sure that the wheel axle is snapped securely into the frame bracket.

Manual Wheel Locks

After several months of use, you may find it necessary to adjust the wheel locks so that they lock securely when engaged. You also may need to adjust them after changing the drive wheel position. Your wheelchair may be equipped with push-to-lock, pull-to-lock, or scissor-style wheel locks. Adjustment instructions for each are outlined below.

WARNING! If your wheelchair is equipped with pneumatic tires, make sure they are inflated to the pressure recommended on the sidewall of the tire.

To adjust each push-to-lock or pull-to-lock manual wheel lock:

1.Disengage the wheel lock. See figure 6. The wheel lock blade should be 0.25 in. (0.64 cm) away from the tire for both pneumatic and solid tires.

2.Loosen the hardware that fastens the wheel lock to the frame. See figure 39.

3.Reposition the wheel lock so that the blade is 0.25 in. (0.64 cm) away from the tire and perpendicular to the plane of the tire.

4.Tighten the hardware that fastens the wheel lock to the frame.
